NAIL-DRIVING- DEVICE.

Application filed September 26, 1922. Serial No. 590,655.

devices for forcing nails into articles to befastened together, as boxes, etc.

The principal object of the invention is to provide a hand operated device, readily portable and capable of driving nails of various kinds and sizes, in an easy and rapid manner wherever it may be desired.

A further object is to produce a device so simple in its nature as to admit of its use by inexperienced persons without difficulty.

Another aim is in the provision of means for facilitating the feed of the nails automatically and for releasing the same from their chute individually, immediately in advance of the action of the driving element.

These several objects are attained by the novel design and construction of parts hereafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which V Figure 1 is a side elevational view of a nail driving device made in accordance with the invention, .partially in section to show the construction.

Figure 2 is a transverse sectional view taken on line 2-2 of Figure 1.

Figure 3 is a fragmentary side view of the driver head.

The device, as shown in the drawing, consists of a base or platform 5, which may be of any preferred shape, having a flat bottom and top upon which the parts to be nailed may be rested, as the box shown.

A cylindrical column 6 is fixed rigidly in the base, near one edge and movably mounted on the column is a sleeve 7 which can be raised or lowered and turned as desired, said sleeve having a boss 8 provided with a winged set screw 9 for clamping when in adjustment.

Attached near the top of the sleeve 7 is a ring or band 10 having a forked lug 11 carrying a pivot pin 12 acting as the fulcrum of a lever 13 having an extending handle 1e and formed in the lever, near its pivot point, is an elongated slot 15.

Apin 16, operating" in the slot, is fixed in a forked head 17 carrying a set screw 18 by which is engaged a rod 19 sliding in a sleeve 20 held in upper and lower supports 21 and 22 secured on the sleeve 7 by set screws or other fastenings as shown.

A coiled expansion spring 23 encircles the upper end of the rod 19 abutting respectively the support 21 and head 17, thus normally raising the rod and lever, a collar 24 on the lower end of the rod limiting its upward movement, and the end of the rod is tapered to form a driver 25.

If relatively large nails are to be driven, a supplementary driver 26 having a conical lower portion 27 is used, the driver being provided with a tapering hole suited to en gage the element 25.

Also adjustably fixed on the sleeve7, at its lower end, is a plate 28 having part of its upper surface bevelled, as at 29, and fixed to the bevelled surface is a strip 30 held by screws 31, a mating strip 32 being firmly secured adjacently parallel by raised cross pieces 33, thus forming a trackway in the space 34 between them, for the nails, the heads of which rest upon the inclined sur faces of the strips 30 and 32, notches 35, at the lower ends of the strips, registering with the lower axis of the rod or ram 19, permitting passage of the head at that point.

Pivoted on pins 36 below the strips are opposed jaws 37 in which are set studs 38 carrying the ends of a coiled tension spring 39 which normally closes the jaws at the front to intercept the advancing nails at the openings 35. V

Secured to the collar 24 is a wedge shaped jaw opener 4.0 its extreme shar end ll moving down with the rod 19 an jaws as the nail heads are passed through,

In operation, the space 34 is filled with nails, their points being pendant and due to the inclination of the strips 3032 and ar of acting the device, the nails are fed forward directly under the driver 25, which upon depressing the lever forces the nail into' the work parts in an obvious manner.

As the sleeve 7 and its associated parts are adjustable in height and also can be rotated relative to the base, a large variety of aropening the,

ticles can be operated upon in a convenient manner.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A nail driving device comprising a base adapted to support work parts, a column on said base, a sleeve adjustable on said column, a second sleeve supported at a spaced distance from the first sleeve, a driver rod slidable in the lastnamed sleeve, means for actuating said rod, means for normally holding said rod in a raised position, an inclined trackway for feeding nails to said driver rod, spring actuating jaws for intercepting the nails in position to be driven, and means for opening said jaws co-incident with the downward movement of said driver rod.

2. A portable nail driving device comprising a base, a column rising therefrom, a sleeve adjustable on said column, a lever pivoted on said sleeve, a rod operated by said lever, a driver formed with said rod, means for guiding said rod relative to said sleeve, an inclined chute for nails carried by said sleeve, spring impelled jaws receptive of the nail to be driven associated with said chute, and means for releasing the jaws from the nail co-incident with the descent of said driver.

3, A portable nail driving device comprising a base, a column rising therefrom, a sleeve adjustable on said column, a lever pivoted on said sleeve, a rod operated by said lever,

a driver formed with said rod, a supple mentary driver engageable with the main driver, a tubular guide for said rod, said guide being engaged with said sleeve, a plate fixed on said sleeve, a pair of spaced nail supports secured in an inclined position on said plate, raised connections between said supports, a jaw pivoted below each support, a spring driving said jaws together to grasp a nail, and a jaw opener fixed on said rod in the plane of said driver.

In witness whereof I have affixed my signature.
